The 48-year-old filmmaker said he isn't too upset that his DC Comics movie has been slammed by critics because he had the "best experience" he's ever had on a set.
Mr Ayer tweeted in response to the critics:
Prefiero morir de pie que vivir de rodillas - Emiliano Zapata? David Ayer (@DavidAyerMovies) August 2, 2016
He then explained what his tweet meant:
Zapata quote is my way of saying I love the movie and believe in it. Made it for the fans. Best experience of my life.? David Ayer (@DavidAyerMovies) August 2, 2016
The reviews may not influence the box office opening considering the buzz surrounding the story, which sees supervillains like The Joker, Harley Quinn, Captain Boomerang and other recruited by a government agency to save the world.
The squad comprises Will Smith as Deadshot, Margot Robbie as Harley Quinn, Jai Courtney as Captain Boomerang, Adewale Akinnuoye-Agbaje as Killer Croc and Jay Hernandez as El Diablo.
The cast also includes Cara Delevingne as Enchantress and Jared Leto as The Joker.
Some loyal fans have even taken out their anger by starting a petition to shut down review aggregator website, Rotten Tomatoes, where the film's current rating stands at 33 per cent.
